To all whom zlt'may concern:

Be it known that I, HERMAN L, KUTTER, a citizen of the United States, and a resident of Hamilton, Ohio, have invented certain new and useful Improvements in Paper-Making Machines, of which the following is a specification. I

My invention relates to paper-making machines of that class known as Fourdrinier machines, wherein the making-wire is vibrated laterally by a shake-frame to cause the fibers of pulp to become interlaced thereon; and the objects of my improvement are to support the shak'-frameat its ends, to

strengthen the side rails by means of trusses, to dispense with intermediate floor-supports, for the front.

to provide extensible supports end of the shake -fra'n1e, and to provide mechanism to vertically adjust the front end of the shake-frame during the operation of the machine. These objects are attained in the following-described manner, as illustrated in the accompanying drawings, in Which-'- Figure 1 is a side elevation of the shakeframe supported at its ends by a fixed frame and extensible supports; Fig. 2, a front elevation of the extensible supports, with breastroll frame mounted thereon with parts re moved; Fig. 3, a side elevation of one of the extensible supports, showing the end of the breast-roll and the breast-roll frame thereon, together with portions of theshake-frame.

In the drawings, 11 represents the shakeframe, pivotally'mountedat its front end on breast-roll frame 12 and atits rear end on fixed or couch roll frame 13. Side rails 14 are undertrussed by means of struts 15 and tie-rods 16, that are adjustable by means of turnbuckles 17, to prevent the side rails from sagging. Table rolls 18 are journaled in bearings, (not shown,) that are removably attached to the side rails in the usual manner. Wire rolls 19 are removably journaled in bearings on corresponding struts under the rails. Making-wire 21 forms an endless apron that is driven by the usual couch-roll (not shown) and around the breast-roll 22, with its upper run over the table-rolls and its under run carried by the wire rolls. The breast-roll frame is provided with an overhanging bracket portion, with the recess for V from the bottom or below the bracket.

Serial No. 723,735. (No model.)

the journal of the breast-roll in the under side, so that the breast-roll may be inserted the roll has been inserted the journal-block is placed in the recess, and a bolt is placed in holes in the walls of the recess, so'as to support the block and roll. An adj ustably-supported roll 23 is arranged to take up the slack in the making-wire in the ordinary manner. Save-all trough 24 is formed in sections and supported under the table -rolls on floorstands 25. Deckle-straps 26 travel through Wash-troughs 27, guides 28, and around pulleys 29. Deckle-bars 31arelaterally adjustable by means of screws 32, that are operated through bevel-gears 33 by cross-shaft 34, with hand-wheel 35 thereon. Apron 36, attached to the breast-roll frame, receives the pulp from the stationary feed-box 37 and di charges it on the making-wire just over the breast-roll. Standards 38 are journaled by means of trunnions 39, formed thereon to oscillate in fixed floor-bearings 41. Brackets 42, formed on opposite sides of eachstandard,extend upwardly therefrom and terminate onopposite sides of the breast-roll frame in the form of guides 43, that are parallel with ea'ch'other. Open slots 44 are formed in the top of the guides and in the same vertical plane. Aworm-Wheel 4 5 is mounted on the top of each standard, with one end of its hub over vertical hole 46 therein, and an adjusting-screw 47 is threaded through the hub of each worm-wheel and movably extends within the opening or hole 46 thereunder. A cylindrical transverse bar 48, with flattened ends 49, that move in slots 44 of the guides, is formed on the top of each screw, whereby the movements of the screws are limited to vertical adjustments only, Said bars are seated in transverse grooves 51, formed in the under edge of the breast-roll frame and nearits ends,so that said frame may be properly supported thereon. Wormshafts 52 are journaled in bearings 53 on the respective standards 38 and arranged to rotate the worm-wheels thereon and effect the vertical adjustment of the screws 47 and the breast-roll frame. Cross-shaft 55, provided with hand-wheel 56, spans the distance between the standards and communicates motion through miter-gears at its ends to both After,

of the worm-shatts simultaneously. lrojecting bar .58 is either formed integral with or secured to one of the standards and is oscil:

lated in a vertical plane by the usual eccen-- tric mechanism (not shown) or otherwise.

and recipi'ocates the breast-roll frame thereon. As the front end of the shake-frame is mounted on the breast-roll frame, it is given the proper amount of lateral shake by the reciprocation of said frame to cause the fibers of pulp on the making-wire to become properly interlaced in transit toward the fixed frame. The lateral vibration of the shakeframe is so short that the vertical arc de-Q:

scribed in its movement is not appreciable anddoes not prevent the even distribution of the pulp on the making=wire.

A vertical adjustment of the front end of the shake-frame is required for the use of' pulp of different grades. For this purpose the standards are made extensible by the adthe worm-gear mechanism and are simu'l-ta neously adjustable by means of the crossshaft and hand-wheel that communicate with them through the miter gears at each end. Itis evident that the adjustment of the shake is in operation, and the amount of adjustment; may be regulated with much precision by the observation of the pulp in motion.

Having fully described my improvement,

' whatI claim as my invention, and desire to seeureby Letters Patent of the United States, A .is- I I bar, and a breast-roll frame on said'bars. justment of the screws therein by means of the guides, means for moving the wormwheels in unison, and a breast-roll frame supported on said transverse bars;

2. In apaper-n'ia-king' machine, the combi- 5o nation, with oscillatory standards, the bottom of each of which is provided with a jour nal-bearing and the upper end is formed into guides andslottedf'vertically andtheinter- I mediate portion is provided with horizontal and vertical recesses and with a laterally-pro- ;jecting bar, a worm-wheel in the horizontal recess, a screw in the vertical recess the upper'end of which is provided'with a transverse 6o '3. In a paper-making machine, the combi- 1 nation, with oscillatory standards, each of which is provided with means for adjusting theheight of the breast roll frame, of a breasts roll frame thereon,said frame being provided 7 Lwith overhanging brackets, the opening" for frame may be-accomplished-while the machine r each of which is down-ward, a bolt through the walls of said opening, and a breast-roll journaled inthe brackets above said bolts.
